Antique Mathematical Loga Cylindrical Calculator Slide Rule - Exc,
Item History & Price
| Reference Number: Avaluer:452146 | Country/Region of Manufacture: Switzerland |
Wow. This is a very beautiful instrument. I have no idea how to use it but I have looked into mathematical equipment and most Loga Calculators (Rechenwalze Loga) I have seen are fairly worn or even deteriorated. This one has bright and clean markings everywhere. It moves smoothly. All of the thin bars are delicately made but they are all solid and in great sturdy shape. If you are a collector of mathematical equipment or calculators than this really is a must. I would call it mus...eum quality. Buyer pays for shipping (price is usually factored at the end of the auction). NOTE: I have already carefully packaged this item so there will be no damage over the week of the auction. That means I cannot take it out to inspect it further but please ask any questions. The photos are large and clear and should give you a good idea of its condition. I do not know the year or model but I'm sure someone out there can tell me. (Maybe circa 1925?) Also it comes with two sturdy plates in good condition that fit into the holder at the bottom. Good luck. I ship all over the U.S. but I am willing to ship to Canada and Europe as long as buyer pays full shipping and insurance. Please message me first to inquire on shipping cost.
Note from online museum site: The Swiss firm of Heinrich Daemen-Schmid manufactured approximately 30, 000 cylindrical Loga-Calculators between 1900 and 1935. Daemen-Schmid patented the device in the United States in 1912. (By the way, there is this same model online at this museum site I just read. The donor of that Loga bought it in 1925 for... wait for it.... $500! He was an international banker and needed it to do logarithms for currency exchange. $500 is a lot of money today. Can't imagine what that was like back then.)
By the way, I have not attempted to clean this item in any way. It probably could look even brighter with cleaning. It's been in my attic for the past couple years. (key words: stanley fuller thatcher slide rule scientific equipment math computing computer antique)
